IMPROVEMENT IN BELLOWS.

Speccation forming part of Letters Patent No. 38,850, dated June 16,1863; antedated September 1, 1862.

To all whom it may concern:

Be it known that we, B. BOEKLEN, of Brooklyn, in the county of Kings andState of New York, and L. PLANER, of the city, county, and State of NewYork, have invented a new and useful Improvement in Bellows; and we dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure l is alongitudinal vertical and central section of our invention. Fig. 2 is ahorizontal section of Fig. 1, taken in the line x x. Figs. 3 and 4. showmodieations of our invention. v

Similar letters of reference indicate corre- .sponding parts in theseveral figures.

The object of this invention is to prevent dust and tire or heat bringdrawn or sucked into the bellows when the latter are iu use and aredistended or expanded for inflation. This drawing in of the dust andheat greatly injures the bellows, and soon destroys them, the heatdrying the leather and causing it to crack, and the dust in a short timeclogging and preventing' the proper action of the valves.

The within-described invention consists in the employment or use of twoball-valves applied to the bellows in a novel way, as hereinafter fullyshown and described, whereby the desired result is attained by a verysimple means, which may be applied economically, and which will not beliable to get out repair nor become deranged by use.

To enable those skilled in the art to fully understand and construct ourinvention, we will proceed to describe it.

A, Figs. l and 2, represents a doubleacting bellows, having stationarytop and bottom plates, c b, with a central moving plate, c, the latterserving as a partition and dividing the bellows into two compartments, cd. The top and bottom plates, c b, have each a valve, e, which opensinward. In the outer end of the bellows A, adjoining the nozzle B, thereis fitted a box, C, which contains two ball-valves, f j'. The box O isprovided with a horizontal central partition, g, which forms twovalve-chambers, h h., one communicatingwith each compartment of thebellows, and both Valve-chambers communicating with the nozzle B, asshown clearly in Fig. l.

From the above description it will be seen that when the plate c israised or forced upward the air inthe upper compartment, c', will beforced through the upper valve-chainber h, as indicated by the arrows,the outer part of this as well as the other valve-chamber havingpassages t', as shown in Fig. 2, for the air to escape. rlhe valvesfbear against stops j when the air is being forced through theirrespective chambers. When air is being expelled from the uppercompartment, c, of the bellows, the lower compartment, d, is beinginiated, the valve c of the latter opening inward, and its ballvalvej'drawn snugly against its seat r, thereby preventing the admission of re,heat, or dust into the compartment d while being inated. This valvulararrangement may be applied to bellows at a small cost, and it will addgreatly to their durability, as the bellows may always bekept clean orfree from trash and dust and the leather prevented from being injured byheat or iire, as is the case to a greater or less ex tent with ordinarybellows.

By the arrangement of the ball-valves ff in the box O, as shown anddescribed, a very durable device is obtained for the purpose. There areno parts liable to be injured by heat, nor by ordinary wear.

We do not claim, broadly, and irrespective of the construction andarrangement herein shown and described, a bellows provided with valves,for they have been previously used,- but What we do claim as new, anddesire to secure by Letters Patent, is-

The employment or use of the ball-valves f f, placed in a box, C,provided with a central partition, g, and applied to the double-actin gbellows, as and for the purpose herein set forth.
